Using Slack (Reaction on message) in a public/external (more than one company) channel?

Hey there,

 

Zev here, I’m new with a quick question! I’m trying to build a Zap that when someone leaves a specific emoji reaction on a Slack message, it triggers. However, it seems the Zap is failing since the channel is external, meaning folks from other companies are inside.

 

Does anyone know a workaround here?

@zevzoldan-postscript you might be able to get it to work by subscribing to the reaction_added event using the Slack Events API. More info here:

https://api.slack.com/events/reaction_added

The biggest challenge is the Slack Request URL verification challenge which must be performed to activate the subscription. That cannot be done with the Webhooks trigger in Zapier. You may need to create a custom Zapier app to pull this off.
